Step 1. Calculate the permutations.
When n objects are taken into consideration, the number of permutations is given by,
P(n,r)=n!(n-r)!
We have to find permutations of abcd taken 3 at a time.
P(4,3)=4!(4-3)!=4×3×2×11=24
Step 2. Figure out the combination..
The number of combinations of n objects taken r at a time is given by,
C(n,r)=n!r!(n-r)!
We have to find combinations of abcd taken 3 at a time.
C(4,3)=4!3!(4-3)!=4×3×2×13×2×1×1=4
Hence, the permutation and combination are 24 and 4respectively.
